86830446 divided by 387 
The aim is to understand the frequency of 387 in 86830446.

Let's proceed to step 1:
387 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 387

On to step 2:
The number 387 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 387

Step 3:
The number 387 fits into 868 2 times, leaving a remainder of 94.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 774 from 868, we get 94.
Fetch the next digit (3) from the dividend, attach it to 94 and continue: 943 / 387

Let's proceed to step 4:
387 goes into 943 2 times with a remainder of 169.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 774 from 943 and we're left with 169.
Include the next digit (0) from the dividend after 169, then repeat: 1690 / 387

Going ahead to step 5:
The number 387 fits into 1690 4 times, leaving a remainder of 142.
The next digit of our result is 4. 
Result so far: 224.0
The remainder is 142 after subtracting 1548 from 1690.
Include the next digit (4) from the dividend after 142, then repeat: 1424 / 387

On to step 6:
The number 387 fits into 1424 3 times, leaving a remainder of 263.
Record the quotient 3 as the next digit in the result. 
Result so far: 2243.0
Subtract 1161 from 1424 to get 263.
Include the next digit (4) from the dividend after 263, then repeat: 2634 / 387

Advancing to step 7:
387 goes into 2634 6 times with a remainder of 312.
Put 6 as the next digit of the answer. 
Result so far: 22436.0
The remainder is 312 after subtracting 2322 from 2634.
Take the next digit (6) from the dividend and append it to 312, then repeat: 3126 / 387

Advancing to step 8:
The number 387 fits into 3126 8 times, leaving a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 224368.0
Subtract 3096 from 3126 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
If we divide 300 by 387, we get 0 and a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 224368.0
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 10:
387 can be fit into 3000 7 times, resulting in a remainder of 291.
Put 7 as the next digit of the answer. 
Result so far: 224368.07
Subtracting 2709 from 3000 leaves us with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Step 11:
2910 divided by 387 is 7 with a remainder of 201.
Record the quotient 7 as the next digit in the result. 
Result so far: 224368.077
Deduct 2709 from 2910 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

In conclusion, the division gives 224368.077 with a balance of 0.0201.
